GISP 1: Conceptual Foundations
Datum Shift
A exchange from one datum to some other, consisting of from NAD27 to NAD83, that could
result in tremendous horizontal shifts of point positions
Data
symbols that constitute measurements of phenomena
Geoid
shape that the earth's surface could take below the impact of the gravity and rotation of Earth by
myself, if other affects which include winds and tides have been absent
Discrete Data
-has recognized and definable barriers
-easy to define exactly where object starts and ends
-usually nouns
-Discontinuous
-Numerical information values that can be COUNTED
Parallels
Another name for lines of latitude
Information
facts that has been decided on or created in response to a question (e.G. Area of a constructing
or a course is data, till it's far needed to dispatch an ambulance in reaction to an emergency.)
Ellipsoid
-Closed surface
-All plane pass sections are either ellipses or circles
,-symmetrical about 3 collectively perpendicular axes that intersect on the center
What are three different names by which "discrete records" can be acknowledged?
Categorical Data
Discontinuous Data
Thematic Data
Lambert Conformal Conic
Map projection on which SPC machine is based totally
Information Systems
computer-primarily based tools that assist people rework records into records
Sphere
-round stable parent
-each point on its surface equidistant from its center
non-stop facts
-Each region on the floor is a measure of the awareness degree or its courting from a hard and
fast factor in space or from an emitting supply.
-Numerical facts values that can be MEASURED
-Transition between feasible values on a continuous surface is without abrupt or
properly-defined breaks
Geomatics
Scientific time period for accumulating, storing, processing, and turning in geographic records
-Geomatics university curriculum fwould include land surveying & geodesy, faraway sensing,
photogrammetry and other clinical studies.
Fake northing
A price implemented to the starting place of a coordinate gadget to change the y-coordinate
readings
, What are four other names via which non-stop statistics is thought?
Continuous floor, area records, nondiscrete information, or surface data
Geographic Information System (GIS)
-computer-based device used to help humans transform geographic information into geographic
data.
-decision support device that mixes attribute records coping with competencies of relational
database control structures with spatial facts coping with abilities of CAD and desktop mapping
structures (David Cowen, 1988)
-enables decision makers to become aware of locations or routes whose attributes fit a couple
of criteria, even though entities and attributes can be encoded in many distinct records
documents.
What is the Difference Between Geomatics and GIS?
-Focus of Geomatics is primarily based on products, services and tools worried in the collection,
integration and management of geographic statistics.
-GIS places information collection, storage, evaluation and visualization into movement.
Universal Polar Stereographic (UPS) grid gadget
a grid system that divides the polar area into a series of one hundred,000-meter squares, similar
to the UTM grid gadget
DBMS
Database Management Systems
What are two examples of non-stop facts?
-Elevation
-Temperature
What disciplines are related to Geomatics?
Land surveying
Remote sensing
Cartography
GPS
Photogrammetry
Geophysics
Geography
